Fig 3. Retinal histology of the injection and non-injection sites at day 70.

In eye injected with hWJ-MSCs, there was a generalised preservation of outer nuclear layer (double-headed arrows) over the whole retina as shown at the site of injection (A), middle region (B) and at the site furthest away from the site of injection (C) at day 70. The site of injection was evident by a small remnant subretinal bump (red arrow). This showed that the preservation of outer nuclear layer is not limited to the injection site. Scale bar represents 50 μm.
